### 4. Functionality

The EGPU-3201-C1-A71 functions as a bridge between an M.2 PCIe interface and dual USB 3.0 ports. It converts the PCIe Gen2 x1 signal from the M.2 slot into two independent USB 3.0 channels, enabling high-speed peripheral connectivity in embedded or industrial systems.

How It Works:
1. The module is inserted into an M.2 B+M key slot on the host motherboard.
2. It utilizes the PCIe 2.0 interface to communicate with the system.
3. The onboard controller translates PCIe signals into USB 3.0 protocol.
4. Two USB 3.0 ports are exposed via a 19-pin header, allowing connection to external USB devices.
5. Optional external power input enhances current output capability for high-power USB peripherals.

Use Cases & Applications:
- Embedded systems requiring additional USB 3.0 ports
- Industrial PCs and automation controllers
- Edge computing devices and IoT gateways
- Digital signage and kiosk systems
- Network appliances and data acquisition systems
- Compact computing platforms where space and power efficiency are critical
